Accessibility of Nonlinear Time-Delay Systems [PDF]
, 2017 A full characterization of accessibility is provided for nonlinear time-delay systems. It generalizes the rank condition which is known for weak controllability of linear time-delay systems, as well as the celebrated geometric approach for delay-free ...

Contract delay: what is it and how are we performing?
Australasian Journal of Construction Economics and Building, 2012 This paper examines the management of contract delays in the construction industry as currently practised, and suggests some best practice alternative methods.Research results about the level of contractor’s time management skills were analysed to ...

Delay-Dependent H∞ Filtering for Singular Time-Delay Systems
Discrete Dynamics in Nature and Society, 2011 This paper deals with the problem of delay-dependent H∞ filtering for singular time-delay systems. First, a new delay-dependent condition which guarantees that the filter error system has a prescribed H∞ performance γ is given in terms of linear matrix ...

Estimation of time delay by coherence analysis [PDF]
, 2004 Using coherence analysis (which is an extensively used method to study the correlations in frequency domain, between two simultaneously measured signals) we estimate the time delay between two signals. This method is suitable for time delay estimation of

Frame delay and loss analysis for video transmission over time-correlated 802.11A/G channels [PDF]
, 2007 This paper presents simulation results for the transmission of unicast MAC frames over 802.11a/g. Fading channel models at various Doppler frequencies are developed to generate time- correlated SNR waveforms.

Minimum-Spanning-Tree-Based Time Delay Estimation Robust to Outliers
IEEE Access, 2023 In this paper, we present a novel approach to estimating multiple time delays (TDs) in sensor arrays that is robust to outliers of TD measurements. These measurements are typically obtained from the peak of the cross correlation of two sensor signals but

Integrability for Nonlinear Time-Delay Systems [PDF]
, 2016 In this note, the notion of integrability is defined for 1-forms defined in the time-delay context. While in the delay-free case, a set of 1-forms defines a vector space, it is shown that 1-forms computed for time-delay systems have to be viewed as ...

Effects of dark energy and flat rotation curve on the gravitational time delay of particle with non-zero mass [PDF]
, 2016 The effects of several dark energy models on gravitational time delay of particles with non-zero mass are investigated and analytical expressions for the same are obtained at the first order accuracy.

Finite-time stability of discrete-time systems with time-varying delay [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2012 Finite-time stability can be used in all applications where large values of the state are not acceptable. In this paper, finite-time stability problem for a class of linear time-varying delay systems is studied. Based on Lyapunov-like functions method
